# ORACLE DOCKERFILES PROJECT
# --------------------------
# This is the Dockerfile for Oracle JDK 23 on Oracle Linux 9
#
# REQUIRED FILES TO BUILD THIS IMAGE
# ----------------------------------
# This dockerfile will download a copy of JDK 23 from
#    https://download.oracle.com/java/23/latest/jdk-23_linux-<ARCH>_bin.tar.gz
#
# It will use either x64 or aarch64 depending on the target platform
#
# HOW TO BUILD THIS IMAGE
# -----------------------
# Run:
#      $ docker build -t oracle/jdk:23 .
#
# This command is already scripted in build.sh so you can alternatively run
#      $ bash build.sh
#
# The builder image will be used to uncompress the tar.gz file with the Java Runtime.
